1944 Wheat Cent -- DDO?

(Since I'm posting five different cents, I thought it would be more convenient to post them all in one thread rather then make five duplicates. They all seem to exhibit the same type of doubling.)

I believe I might have found a few "Class 6" doubled dies from a batch of wheat cents, Some of them look to me like they might be post-mint damage however, so I wanted to be certain. They all seemed to be doubled in the date, especially on the "9", so I magnified that area on each of them.


Wheat cent 1: This one struck me as being the most doubled out of the five, Most noteably on the tail of the 9 in the date.







Wheat cent 2: The 9 on this one seemed doubled at the top and bottom, or possibly just worn.







Wheat cent 3: This looked to be a minor DDO on the 9 in the date.







Wheat cent 4: Possible minor DDO, Tail of the 9.







Wheat cent 5: This one confuses me the most, The tail of the 9 looks flattened, So I believe it to be post-mint damage, but it also looks thicker then usual.








Thanks again!
